Description

  The present invention relates to a fishing line guide that is attached to a fishing rod and guides a fishing line fed from a reel.

  Conventionally, a fishing line guide for inserting and guiding a fishing line fed from a reel at a predetermined interval in the axial direction is mounted on an outer peripheral surface of a fishing rod called an outer guide method. Many of such fishing line guides are constituted by a frame having an annular holding portion and a supporting leg portion, and a guide ring attached to the annular holding portion.

  For example, in Patent Document 1, a vertical surface is formed on the outer peripheral surface of the guide ring, and an inclined surface is formed from an edge of one surface toward the vertical surface, and the concave portion is defined by the vertical surface and the inclined surface. A fishing line guide is disclosed in which an annular holding portion of a frame is engaged. According to this fishing line guide, when the guide ring is locked to the annular holding portion of the frame, the surface of the annular holding portion of the frame is engaged so as to contact the vertical surface of the ring-shaped recess.

Shoko 58-46288

  According to the known guide ring described above, by forming the inclined surface on the guide ring, it is possible to guide the guide ring to the vertical surface side with respect to the annular holding portion, thereby making it difficult to drop the guide ring. Although it is possible, since the engagement state of the guide ring is not stable only by being brought to the vertical surface side, there is a possibility that the guide ring is loose or misaligned after being attached to the annular holding portion.

  The present invention has been made paying attention to the above-described problem, and provides a fishing line guide in which the guide ring does not rattle or shift with respect to the annular holding portion of the frame that holds the guide ring. With the goal.

  In order to achieve the above-described object, the present invention provides a fishing line guide in which a concave portion provided along an outer periphery of a guide ring is engaged with an annular holding portion of a frame. A perpendicular inner surface that is a perpendicular direction, an inclined inner surface that descends toward the deepest portion of the recess, and an inclined receiving surface that rises from the deepest portion toward the vertical inner surface. The inner peripheral surface of the annular holding portion of the frame is supported by the inclined inner surface of the recess and the receiving surface.

  The concave portion formed in the outer peripheral portion of the guide ring in the fishing line guide described above includes a vertical inner surface that is perpendicular to the axis, an inclined inner surface that descends toward the deepest portion of the concave portion, and the deepest portion. And an inclined receiving surface that rises from the portion toward the vertical inner surface. When such a guide ring is mounted on the annular holding portion of the frame, the annular holding portion is brought close to the vertical inner surface side by the inclined inner surface to hold the guide ring and the inner periphery of the holding portion. Since the surface is reliably supported in the front-rear direction (the direction through which the fishing line is inserted) by the inclined inner surface of the concave portion of the guide ring and the receiving surface, the guide ring is prevented from being loose or displaced.

  According to the present invention, a fishing line guide can be obtained in which the guide ring does not rattle or shift with respect to the annular holding portion of the frame that holds the guide ring.

Hereinafter, embodiments of the fishing line guide according to the present invention will be specifically described.
FIGS. 1 to 5 are views showing an embodiment of a fishing line guide according to the present invention, FIG. 1 is a rear view, FIG. 2 is a side view showing a mounting method of a guide ring, and FIG. 3 is a fishing line guide shown in FIG. 4 is a rear view showing the frame structure, FIG. 4 is a side view of the fishing line guide shown in FIG. 1, and an enlarged view of the main part. FIG. 5 is an enlarged view of the engagement state between the guide ring and the annular holding part of the frame. It is a figure shown. In the following embodiments, the front-rear direction (fishing line insertion direction) is defined with the left side in FIG. 2 as the tip side (front side) and the right side as the proximal side (rear side).

  The fishing line guide 1 includes a frame 2 having an annular holding portion 2a and a support leg portion 2b, and a guide ring 10 attached in the holding portion 2a.

  The frame 2 can be integrally formed of, for example, titanium (pure Ti), various known titanium alloys, stainless steel, and the like, and as described above, the annular holding portion 2a and the annular holding portion 2a. And a supporting leg 2b extending downward from the holding portion. The support leg portion 2b supports the annular holding portion 2a on both sides in the radial direction, and a pair of leg portions 2d extending so as to approach each other downward on each side portion, and a pair of leg portions The lower end of 2d has a foot 2e bent in a substantially horizontal direction. The foot portion 2e has a mounting surface 2f for a fishing rod on the back side thereof, and the foot portion is fixed to the outer peripheral surface of the fishing rod R with a spool 7 or the like. In addition, after thread winding 7, a resin 8 for thread fixing is attached.

  The annular holding portion 2a of the frame 2 has a width L1 larger than its thickness L2, and has a circular hole 3 to which the guide ring 10 is attached. In addition, the annular holding portion 2a is cut at an arbitrary position (in this embodiment, the lower end position as shown in FIG. 1) with a predetermined gap, so that the hole 3 is formed from the outside. A notch portion 4 is formed which leads to. In the figure, each of the ends (claw-like projections) of the cut annular holding portion 2a is indicated by reference numeral 4a. The notch portion 4 has a front end surface 4b of both end portions 4a with a predetermined gap. It is formed by facing each other. The thickness L2 of the holding portion 2a of the frame 2 is the thickness (length) in the front-rear direction in which the fishing line is inserted by attaching the fishing line guide 1 to the fishing rod, and the width L1 is the radial width of the annular holding portion 2a. (Length).

  The both end portions 4a are formed in a tapered shape. Here, as shown in FIG. 1, the tapered shape is one in which the width L1 decreases as it moves to the tip in front view, the thickness L2 decreases as it moves to the tip, or as it moves to the tip. In the present embodiment, as shown in FIG. 1, the bottom portion constituting each end portion 4a is configured such that the rigidity becomes smaller as the width and thickness become smaller. The edges 4 c extend in a substantially horizontal direction, and the upper edges are configured as arcs defining the holes 3, thereby forming a tapered shape. In the present embodiment, the rear surface 4d and the front surface 4e at both end portions 4a are also closer to each other as they move to the front end, and the thickness is reduced, resulting in a tapered shape (see an enlarged view of FIG. 4).

  In addition, the frame 2 is formed with a large width L1 of the holding portion 2a connected to the portion where the cutout portion 4 is formed (both end portions 4a) in the range from the holding portion 2a to the left and right support legs 2b. An extended portion 2A is formed. In the present embodiment, as described above, since the cutout portion 4 is the lower end position of the holding portion 2a, the extension portion 2A is positioned on both the left and right sides of the holding portion 2a (holding portion) as shown in FIG. It is gradually formed wider from a horizontal side position passing through the center position of 2a; indicated by a symbol P) toward a lower position where the notch 4 is formed. In the drawing, such an extended portion is indicated by a shaded portion, a holding portion 2a adjacent to the extended portion 2A is indicated by a hatched portion as a region 2a 'extended by a certain width L1, and a virtual boundary with the extended portion 2A is indicated. It is indicated by a two-dot chain line. The lower end side of the extended portion 2A is a boundary position P1 between the pair of leg portions 2d. That is, the range from the reference symbol P to P1 is defined as the extended portion 2A, and the extended portion 2A has a function of reinforcing both end portions 4a forming the cutout portion 4.

  The extension part 2A is narrowed so that both sides thereof are narrowed from the holding part 2a toward the support leg part 2b and displaced to the support leg part 2b (or the support leg part 2b spreads toward the holding part 2a). The expanded portion 2A is formed with the largest width L1 on the center side toward the support leg portion 2b, and one side thereof is connected to the end portion 4a, and the width L1 gradually increases from the end portion 4a toward the support leg portion 2b.

  The frame 2 having the annular holding portion 2a and the supporting leg portion 2b is integrally formed by punching a metal plate into a predetermined shape by pressing and bending a predetermined portion. Therefore, each part of the frame 2 has a part formed by the upper and lower surfaces of the metal plate to be pressed and a part formed by the cut surface, and is the front and rear surfaces (the tip side surface and the hand side surface) of the frame 2. (For example, the front surface 4e and the rear surface 4d also correspond) are formed by the upper and lower surfaces of the metal plate, and the thickness portion of the peripheral surface (side surface) of the frame 2 is formed by the cut surface of the metal plate.

  The peripheral surface (side surface) of the frame 2 has an outer peripheral surface 2i formed on the outer side of the frame 2 and an inner peripheral surface 2h formed on the inner side of the frame 2, and the outer peripheral surface of the annular holding portion 2a is also included. 2i and the inner peripheral surface 2h, and the inner peripheral surface 2h side in which the hole 3 is formed is engaged with the recess 10c of the guide ring 10.

  The surface of the entire frame is polished by polishing (such as a barrel). Preferably, the peripheral surface (side surface) of the frame is polished at the edge, and the peripheral surface from the front and rear surfaces of the frame 2 is polished. It is formed so as to change through an inclined surface to form a convex curved surface, or as shown in FIGS. 4 and 5, the peripheral surface (outer peripheral surface 2i, inner peripheral surface 2h) is a series of outwards. A convex curved surface is formed.

  The guide ring 10 is a circular ring formed of a hard material such as metal or ceramic, and includes a hole 10A through which a fishing line is inserted. That is, the fishing line is inserted through the guide ring 10 along a line passing through the center of the hole 10A (such a center line is defined as an axis X of the guide ring).

  The guide ring 10 is formed with a pair of flanges 10a and 10b along the outer periphery, and a recess (circumferential groove) 10c is formed between these flanges.

  In the present embodiment, one of the pair of flanges (the front flange 10b) is formed high, and the outer periphery of the guide ring is formed such that the front and rear flanges have different diameters. That is, the height in the direction orthogonal to the axis X with the deepest part (bottom part) 10d of the recess 10c formed between the pair of flanges as the base point is the height H of the front flange 10b and the height of the rear flange 10a. It is formed higher than h, and this causes a step on the outer periphery of the guide ring. The recess 10c is formed by the inner surfaces of the front and rear flanges 10b and 10a with the deepest portion 10d as the center.

  Specifically, the recess 10c is provided along the outer periphery of the guide ring 10 and extends along the X axis extending from the deepest portion 10d toward the outer periphery of the guide ring 10 so as to be in a direction orthogonal to the axis X. A vertical inner surface 10e, an inclined inner surface 10f descending toward the deepest portion 10d of the recess 10c, and an inclined receiving surface 10g rising from the deepest portion 10d toward the vertical inner surface 10e. ing. Here, the vertical inner surface 10e includes not only a direction that is accurately orthogonal to the axis X but also a configuration that is slightly inclined with respect to the orthogonal direction.

  And the vertical inner side surface 10e of the recessed part 10c of the guide ring 10 is supported facing the front surface (or rear surface) of the annular holding portion 2a of the frame 2 so that the guide ring 10 can be moved in the front direction in which the fishing line easily passes. It is supported facing.

  Therefore, the vertical inner surface 10e is formed by the inner surface of the high flange 10b, the inclined inner surface 10f is formed by the inner surface of the lower flange 10a, and the receiving surface 10g is connected to the deepest portion 10d. It is formed by a curved surface that connects the vertical inner surface 10e. Accordingly, the vertical inner side surface 10e and the inclined inner side surface 10f are in directions along the respective directional axes Y2 and Y1 of the flanges 10b and 10a, as shown in FIG.

  In the present embodiment, the inclined inner surface 10f formed by the inner surface of the flange 10a is a downward inclined surface having a slightly concave curved surface from the rear side of the recess 10c toward the deepest portion 10d. It is formed from the upper part to the deepest part 10d, and the receiving surface 10g is also formed of an inclined surface having a slightly concave curved surface from the deepest part 10d toward the vertical inner surface 10e. Thereby, the front and back of the deepest part 10d of the recessed part 10c are comprised as a concave (arc-shaped) curved surface in the width direction (axis X direction) of a recessed part.

  The receiving surface 10g and the inner surface 10f are both inclined surfaces extending in the front-rear direction of the recess 10c from the deepest portion 10d, but the receiving surface 10g is formed to have a lower height from the deepest portion 10d than the inner surface 10f. The

  Further, the guide ring 10 is formed with substantially the same thickness T from the front flange 10b to the rear flange 10a through the deepest portion 10d, and the inner side surface of the hole 10A through which the fishing line is inserted is in the recess. It is formed in a shape corresponding to (according to) the side surface.

  In the configuration described above, when the guide ring 10 is mounted in the annular holding portion 2a, the guide ring 10 is moved back and forth from the flange (rear flange) 10a side with respect to the holding portion 2a (the fishing line insertion direction). Is pressed against the elasticity of the frame 2 (particularly, the elasticity of both end portions 4a defining the notch 4) while the holding portion 2a including the notch 4 is expanded, and the holding portion 2a is Get over the flange 10a and enter the recess 10c. In this case, the press-fitting operation can be easily performed by setting the end surface of the flange 10a to an arcuate curved surface 10m. And the holding | maintenance part 2a which entered in the recessed part 10c is induced | guided | derived to the said downward inclined inner side surface 10f, and is moved below the inclined inner side surface 10f as it recovers from elastic deformation, and the vertical inner side surface 10e. The concave portion 10c is engaged at a position close to the side.

  At this time, the holding portion 2a is close to or in contact with the vertical inner surface 10e. Even when the holding portion 2a is in close proximity, when the holding portion 2a moves in the recess 10c, the front surface immediately approaches the inner surface 10f. The holding portion 2a is kept in contact with the vertical inner side surface 10e. Further, the inner peripheral surface 2h of the holding portion 2a is stably supported by the front receiving surface 10g and the rear side by the inclined inner surface 10f (at least two points) (see FIG. 5). In this case, the guide ring 10 can be supported more stably by matching the axis Y passing through the center of the frame 2 with the deepest portion 10d of the recess.

  According to the configuration described above, the annular holding portion 2a is moved toward the vertical inner side surface 10e by the inclined inner side surface 10f to hold the guide ring 10, and the inner peripheral surface 2h of the holding portion 2a is inclined. The inner surface 10f and the receiving surface 10g are in contact with each other at the contact points S1 and S2, and are reliably supported in the front-rear direction (the direction in which the fishing line is inserted). Misalignment is prevented.

  Further, as described above, since the peripheral surface (inner peripheral surface 2h) of the holding portion 2a is composed of a convex curved surface, when contacting the inclined inner side surface 10f and the receiving surface 10g, It is easier to make contact than to make contact at a square part, and even if the engagement state with the guide ring 10 is shifted, it is easy to maintain the contact state, the support to the guide ring 10 is stabilized, and sudden position movement is prevented. And the support state is stabilized.

  In addition, the peripheral surface (outer peripheral surface 2i, inner peripheral surface 2h) of the holding portion 2a includes a portion where the planar front and rear surfaces of the holding portion 2a change so as to face the peripheral surface side at the edge, and the concave portion 10c On the other hand, the inner peripheral surface 2h abuts on the edge side contacts S1 and S2. Accordingly, the holding portion 2a is supported so as to press the concave portion 10c of the guide ring 10 in the direction of the hole 10A.

  Similarly, since the inclined inner side surface 10f and the receiving surface 10g are also constituted by concave curved surfaces, the contact area can be widened, combined with the contact of the convex curved surface 2h. As a result, there is no sudden displacement and the contact state is maintained, so that the guide ring can be stably fixed.

  The contact points S1 and S2 with respect to the guide ring 10 in the recess 10c on the inner peripheral surface 2h of the holding portion 2a are closer to the axis Y than the front and rear surfaces.

  Further, in the present embodiment, the flanges 10a and 10b having different heights are formed on the outer periphery of the guide ring 10, so that the vertical inner surface 10e on the flange side with a high height is brought close to or close to the holding portion. The direction of the guide ring can be maintained.

  In the fishing line guide having the above-described configuration, the innermost surface (convex curved surface) of the frame 2 supported by the deepest portion 10d of the concave portion 10c of the guide ring 10, the inclined inner side surface 10f of the concave portion, and the receiving surface 10g. ) Since it is possible to form a gap with 2h, it is preferable to fill the gap with the synthetic resin 30. As a result, it is possible to more reliably prevent the guide ring 10 from rattling or shifting. In this case, as shown in FIG. 5, the synthetic resin 30 may be interposed between the inclined inner side surface 10f and the rear surface of the frame (holding portion).

  In the configuration of the present embodiment described above, since both end portions 4a of the annular holding portion 2a are tapered toward the tip, the guide ring 10 is gradually elastically deformed and distorted toward the tip when the guide ring 10 is press-fitted. Therefore, the guide ring can be easily press-fitted. In addition, when the both end portions 4a are elastically deformed during the press-fitting operation, the frame portion is prevented from being plastically deformed and further extended from the expanded portion 2A. The left and right support legs 2b can assist the restoration by pushing back the extended holding part 2a.

  In the fixed state of the guide ring described above, as shown in FIG. 1, the tips of both end portions 4a of the holding portion 2a are located on the radially inner side of the peripheral edge of the flange (the flange 10b having a high height), Since it does not protrude to the outside of the flange, the fishing line is prevented from being caught, and the occurrence of thread breakage or the like is prevented. Even if tension is applied to the inserted fishing line, both ends 4a of the holding portion 2a are distorted while being greatly elastically deformed toward the tip, so that the frame itself is difficult to deform and the tension on the fishing line is reduced. The thread breakage is prevented, and the dropout of the guide ring 10 can be effectively suppressed.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, It can change variously.

  For example, with respect to the inclined inner surface 10f that descends toward the deepest portion 10d of the recess 10c and the inclined receiving surface 10g that rises from the deepest portion toward the vertical inner surface 10e, the inside of the holding portion 2a of the frame 2 The peripheral surface 2h may be configured to abut and support at least at two points, and may be configured as a flat inclined surface as shown in FIG. Moreover, as shown in this figure, you may comprise the holding | maintenance part 2a so that it may contact | abut to the vertical inner surface 10e.

  Moreover, the both ends 4a of the holding | maintenance part 2a do not need to be a taper shape, Furthermore, without forming the notch part 4, the holding | maintenance part 2a may be formed in the continuous cyclic | annular form and the guide ring 10 may be attached.

  The construction material of the frame constituting the fishing line guide, the configuration of the shape and size of the frame portion, and the like are appropriately changed according to the fishing rod and node portion (general rod, middle rod, tip rod) used. It is possible.

  Further, the flange formed on the guide ring can be appropriately deformed with respect to the configuration of the flange as long as it can be effectively press-fitted into the holding portion 2a and can support at least two points as described above. .
